How colors fit together is an art, and a science. The link above has a great tool that creates color schemes.

It has an export capability that allows you to get the colors it generates. Click on “scheme info". If you click on ‘View Source’ (as the page tells you), it has a nice little segment with the CSS colors all set.

These colors are from this scheme: http://colorschemedesigner.com/#4-51WVZrG4mGu

.primary-1 { background-color: #10062E }
.primary-2 { background-color: #110C22 }
.primary-3 { background-color: #09021E }
.primary-4 { background-color: #4C3596 }
.primary-5 { background-color: #604F96 }

.secondary-a-1 { background-color: #1E032D }
.secondary-a-2 { background-color: #190A21 }
.secondary-a-3 { background-color: #13011D }
.secondary-a-4 { background-color: #712E96 }
.secondary-a-5 { background-color: #7B4A96 }

.secondary-b-1 { background-color: #06112D }
.secondary-b-2 { background-color: #0C1222 }
.secondary-b-3 { background-color: #020A1D }
.secondary-b-4 { background-color: #345196 }
.secondary-b-5 { background-color: #4E6496 }

I pasted them into robots.design, as displayed, and got an interesting page.

This is definitely a case where tuning the design colors and those submitted to a better match would be effective.

Theoretically, you could create a greyscale site template and apply nice colors from the ColorSchemeDesigner site - and customize a site very quickly.
